1. Among all the metals that can be rolled into thin metal foils, aluminum metal is the cheapest among all thin metal foils, such as: Cu, al, Au, Ag, Ni, etc. In addition, aluminum foil maintains luster and will not discolor or oxidize for long periods of time at very high temperatures. Therefore, aluminum foil is used as the main packaging material for cigarettes, chocolate, pharmaceuticals, and even hot food packaging in hotels and restaurants.
2. The color of cigarette aluminum foil is divided into gold, silver and gold. In cigarette packaging, aluminum foil is compounded with paper, that is, aluminum foil paper for cigarette packaging. This composite cigarette aluminum foil paper has high softness, good decorative and protective properties, and has become the dominant packaging material for cigarette packaging. Aluminum foil will gradually withdraw from the field of cigarette packaging.
3. Aluminum foil composite paper adopts wet bonding process, which has better production efficiency, economy and environmental protection than dry method and hot melt bonding. Cigarette packaging companies use water-soluble or water-dispersible adhesives to bond o+ to a porous, highly hygroscopic liner, eliminating the problems associated with the use of hydrazine solvents in dry-process applications, such as environmental contamination, residual solvents, Increase exhaust gas recovery and emission devices, etc. , making production processes and products more hygienic and safer.
